I ordered some ugg boots November 4, 2017 and it says that my order would be delivered by December 10, 2017 i have tracked it several times but cant find an exact site to track it on so i seen a site today for tracking and it says that my item is still in customs what does that mean ?! And also December 10th is almost here and i have contacted the seller and im not getting no reply at all and when i go to try to click on the sellers name it says no items available so what is going on i want my order
